Figure 9 failure

I spent the holiday weekend at the in-laws' place up near La Crosse, WI. I of course put up my hammock and spent the three nights outside!
I had my Speer winter tarp up, using an "over the top" ridge line made of Dyneema. The tarp attaches to the ridgeline via prussik loops. I have shock-cord tensioners at all tie-out points.
For stringing up the thing I use a mini-biner at one end and a small plastic figure 9 at the other end.
On Sunday we had a steady wind with gusts up to around 25MPH pretty much all day. At around 3:00pm I just happened to go outside for some reason, and was standing near the hammock when the Figure 9 snapped! Guess the wind gusts were too much for it.

Good to know not to trust those plastic Figure 9's when I'm NOT 20 yards from the house. I replaced it with the next size up Figure 9 in metal.

i bought a 4 pack of plastic figure 9s from REI one time (not paying attention that they were plastic, they were on sale) when i was doing mods to my tarp, i set it up with one and it snapped, from pulling on it to hard,
dont trust the plastic ones, even if they are on sale

I'd guess the bigger the tarp, the bigger the combined force from wind gusts...and the SWT is a good sized sail (err, tarp!)

I can't imagine this happening before the tarp or tabs rip. I have had mine up in these Georgia storms for a week now (won't get dry enough to take it down). It is still completely dry inside and no figure 9 failures.
